Super Bowl week is beginning to resemble one of those family reunions where your crazy uncle says something outrageous, but just true enough to spark a discussion worth having.

Two years ago, it was Steelers linebacker James Harrison ripping the NFL and Commissioner Roger Goodell for excessive fines on the violent hits that were his specialty, and generally trying to make the game too safe. "We'll lay a pillow down where I'm going to tackle them," he said mockingly at one point, "so they don't hit the ground too hard, Mr. Goodell."

This time around, the provocateur was Bernard Pollard, the Ravens' notoriously punishing safety. Covering much of the same ground Harrison had, Pollard said he didn't think the NFL would be around in 30 years because rule changes designed to make it even safer would eventually drive away fans - if something tragic didn't hasten the game's end even sooner.

"The only thing I'm waiting for ... and, Lord, I hope it doesn't happen ... is a guy dying on the field," Pollard told CBSSports.com.

It may be easy to dismiss a handful of players' exaggerated views, but the notion that the NFL is in real trouble - as well as football at every level from Pop Warner up - isn't as hard a sell as it seems.

Sure, the game has never been more popular. The league is taking in nearly $10 billion annually, breaking its own record TV telecasts almost on a weekly basis, and could repeat the feat again Sunday in New Orleans, when the 49ers tee it up against the Ravens. But just a few weeks later, arguments are scheduled to begin in Philadelphia in one lawsuit brought on behalf of former players and their families contending that the league failed to warn them about the dangers of concussions and then concealed those risks even in the face of mounting evidence. And that's just one of several pending legal actions piling up outside Goodell's office door.

Yet even all those lawsuits combined may not represent the most serious threat to the NFL's existence long term.

"The plaintiffs are facing a huge uphill battle, and that's me speaking as a lawyer," said attorney Robert Boland, who teaches sports law at New York University's Tisch Center, and has worked previously as an agent. "Obviously, the publicity generated by the concussion issues is big, but I don't think the same is true in terms of legal liability. This is a collectively bargained issue for the most part and while the NFL is the biggest target - it has the deepest pockets - courts are likely to take a very narrow view of what responsibility it's facing. It may well be the case where the NFL wins in the courts very quickly, then has to find a way to be sensitive to the very real dangers that exist as part of the game.

"The concussion issue is forcing people to choose sides and yet the real challenge, I think, will be holding together the coalition that made the game so popular - players, coaches, parents and fans. There's already a bar for young players to get into the game; the cost of equipment, the staffing it requires, and if the insurers get nervous and drive up the costs even further, that might be the biggest short-term threat. Nothing has shown up yet," Boland added, "but anybody taking the long view has to be looking at the present and saying, `It could.' "
